I've come across many Art Deco filigree brooches but few with colorful enameling as this one has in blues, burgundy and yellow. Brooch is a nice size measuring 1-3/4" x 1-3/8" with a white rhodium finish, most likely over brass. The glass stone is faceted, bezel set and measures about 23mm x 16mm. There are a few super tiny nicks to the stone if viewed closely and one clear stone missing but I am searching for a replacement and will most likely be able to find one. Possible to hang this on a chain as well using the closed pin shaft since it's centered in the back. Overall amazing, truly nice!
